Q. Two identical balls each having a density

ρ

are suspended in vacuum from a common point by two insulating strings of equal length. Both the balls have equal mass and charge. In equilibrium each string makes an angle

θ

with vertical. Now both the balls are immersed in a liquid, as a result the angle

θ

does not change. If the density of the liquid is

σ

, then find the dielectric constant of the liquid.

Two positively charged spheres of masses $m_{1}$ and $m_{2}$ , are suspended from a common point at the ceiling by identical insulating massless strings of length l. Charges on the two spheres are $q_{1}$ and $q_{2}$ , respectively. At equilibrium both strings make the same angle $θ$ with the vertical. Then
